NSW Land Tenure

Summary: \r\nA comprehensive NSW Land Tenure layer has been developed, integrating the latest and most reliable datasets sourced from various governmental authorities and departments. To the best of our knowledge, this layer offers detailed mapping of recent updates and changes in land tenure across the state. It includes information on land allocations, ownership transformations, and management updates, providing an up-to-date and accurate representation of land tenure in New South Wales.\r\n\t\r\nDescription: \r\nThe statewide Land Tenure layer is a comprehensive dataset created by incorporating spatial and aspatial data from various state and commonwealth government departments, organisations and authorities, including the Forestry Corporation of NSW; NSW Department of Primary Industries and Regional Development; NSW Spatial Services; Department of Climate Change, Energy, the Environment and Water (Environment and Heritage); The Australian Department of Agriculture, Fisheries and Forestry (ABARES: SOFR23 & SOFR18); the NSW SEED data portal; and National Park. \r\nThe wall-to-wall spatial feature class demonstrates how land in NSW is being managed or owned. It can also be employed to monitor changes in land management or ownership transfer over time.\r\nThe process of acquiring datasets for updating the tenure layer and creating the statewide layer began in January 2024 and continued until August 2024. The collected datasets were amalgamated, and gaps were filled. This combined layer has then been manually assessed and visually compared against various datasets to ensure its completeness and accuracy. Esri basemaps such as Imagery, Imagery Hybrid, OpenStreetMap, and Google Earth maps were also used for visual assessment. Furtheremore, expert knowledge from government professionals, and land history web search were considered to address potential inaccuracies and unreliability in datasets from various sources.\r\nThe land tenure data consists of seven Tenure classes each class covering various tenure types as below: \r\n\t- Tenure Class: presents tenure classification of the dataset as Crownland-Leasehold; Crownland-Other; Indigenous Owned; National Park; Private; State Forest; Unresolved Tenure.\r\nTenure Type of each tenure class are as follow: Crownland-Leasehold: Crown Timberland Lease; LEASE (SOFR2023); Leasehold Crown Land; Western Lands Lease; Crownland-Other: Crown Road; Crown Waterway; Either Crown Waterway, Road or other; OCL (SOFR2023); Other crownland; Public Road; Reserved Crown Timber Land; Timber Reserve; Vacant And Reserved Crown Land; Vacant Crown Land; Reserve for Public Buildings (Forestry); Indigenous Owned: Aboriginal Area; National Park: Conservation Reserve; Fire trail within national parks; Historic Sites; National Park; Nature Reserve; NCR (SOFR2023); Regional Park; State Conservation Area; Private: Hardwood Joint Venture; PRIV (SOFR2023); Private; Hardwood Plantations; Private Property; Private Softwood Plantation; Profit á Prendre; Softwood Joint Venture; State Forest: FCNSW Ownership; MUF (SOFR2023); State Forest: State Forest OEH Managed Flora Reserve; Unresolved Tenure: null (-2); ND (SOFR2023).\r\n\t- Shape_Area: Area of each Tenure class in square meter.\r\n\tCaveats: \r\n\t- In general, data from diverse sources retains different levels of accuracy, reliability and coverage, therefore, a thorough visual assessment has been carried out to overcome the issue. Having said that, there still could be potential minor errors which could have been missed due to the large extent of the dataset. \r\n\t- Note that Roads, Waterways and general public areas across the Greater Sydney and Wollongong have not been properly mapped in this version. This will be updated in the next update.\r\n

摘要：
本数据集开发了一套完整的新南威尔士州（New South Wales，NSW）土地保有权属（land tenure）综合图层，整合了来自各类政府主管部门与机构的最新且可靠的数据集。据目前所知，该图层可详细绘制全州范围内土地保有权属的最新动态与变更情况，涵盖土地分配、所有权变更及管理更新等信息，能够精准且实时地呈现新南威尔士州的土地保有权属状况。

描述：
全州土地保有权属综合图层是一套综合性数据集，整合了来自州级与联邦政府部门、机构及主管单位的空间数据与非空间数据，涵盖新南威尔士州林业公司、新南威尔士州初级产业与区域发展部、新南威尔士州空间服务局、气候变化、能源、环境与水利部（环境与遗产分支）、澳大利亚农业、渔业与林业部（澳大利亚农业与资源经济科学局ABARES：SOFR23及SOFR18）、新南威尔士州SEED数据门户以及国家公园管理相关机构等来源。
该全覆盖空间要素类可清晰展示新南威尔士州土地的管理模式与权属归属情况，同时可用于长期监测土地管理模式变更或所有权转移动态。
本次权属图层更新与全州图层构建所需数据集的采集工作始于2024年1月，持续至2024年8月。采集完成的数据集已完成整合与空缺补全。随后，研发团队对合并生成的图层开展人工评估，并与多套参考数据集进行可视化比对，以确保其完整性与准确性。评估过程中还借助了Esri影像底图、影像混合底图、开放街道地图（OpenStreetMap）及谷歌地球（Google Earth）地图等工具开展可视化校验。此外，研发团队还结合政府专业人士的专业知识与土地历史网络检索结果，以排查并修正多源数据集可能存在的不准确与不可靠问题。
本土地保有权属数据共包含7类权属类别，每类权属类别涵盖以下多种权属类型：
- 权属类别（Tenure Class）：本数据集的权属分类包括王室土地（Crownland）租赁保有（Crownland-Leasehold）、王室土地（Crownland）其他权属（Crownland-Other）、原住民所有（Indigenous Owned）、国家公园（National Park）、私有（Private）、州立森林（State Forest）及权属待核实（Unresolved Tenure）。
各类权属类别的具体权属类型如下：
- 王室土地（Crownland）租赁保有（Crownland-Leasehold）：王室国有林地租赁、LEASE（SOFR2023）、王室土地租赁保有、西部区域土地租赁；
- 王室土地（Crownland）其他权属（Crownland-Other）：王室道路、王室水道、王室水道/道路或其他权属、OCL（SOFR2023）、其他王室土地、公共道路、预留王室国有林地、木材储备区、闲置预留王室土地、闲置王室土地、公共建筑储备用地（林业用途）；
- 原住民所有（Indigenous Owned）：原住民区域；
- 国家公园（National Park）：保护预留地、国家公园内防火道、历史遗迹、国家公园、自然保护区、NCR（SOFR2023）、区域公园、州级保护区域；
- 私有（Private）：硬木合资林、PRIV（SOFR2023）、私有土地、硬木人工林、私有物业、软木私有人工林、取益权（Profit á Prendre）、软木合资林；
- 州立森林（State Forest）：新南威尔士州林业公司（FCNSW）所有地块、MUF（SOFR2023）、州立森林：新南威尔士州环境与遗产部（OEH）管理的植物群保护区；
- 权属待核实（Unresolved Tenure）：空值（-2）、ND（SOFR2023）；
- 形状面积（Shape_Area）：单类权属地块的面积，单位为平方米。

注意事项：
- 总体而言，不同来源的数据在精度、可靠性与覆盖范围上存在差异，因此研发团队已开展全面的可视化评估以弥补该缺陷。尽管如此，由于本数据集覆盖范围极广，仍可能存在少量未被检出的潜在误差。
- 请注意，本版本未对大悉尼及伍伦贡地区的道路、水道与公共通用区域完成精准制图，该问题将在下一版本更新中修复。
